I bought several copies of a game and can not really give away.

Woodle Tree Adventures was given away for free before, so it has been removed from the giveaway list.
You can't make a giveaway for that game anymore.

Before buying anything to give away always check is it possible to give the game away first. Then check here to see if you'll get full value for the game or only 15%.

well it's just $0.35 wasted...

That game was given away for free like 100 times , I think even now there was 1 site giving it away for free at least i saw some day ago xD

Correct, you should have checked first.

Gotta do your research =/

Refund them.
